The short answer: a typical electrical panel upgrade in Chicago costs around $4,500, with half of all projects landing between $2,500 and $7,740. If a quote falls well outside that range, it isn't automatically wrong — but it deserves an explanation you can understand.
Every figure on this page is computed from declared valuations on building permits published by Chicago's open-data portal. We report the 25th percentile, median and 75th percentile of 2,872 recent residential filings — never a single-point "average". Declared values are what applicants file, not final invoices, so treat the range as planning guidance rather than a quote. Full methodology →

Because identical-sounding projects legitimately differ in size, specification and site conditions. That is why we publish the 25th percentile, median and 75th percentile instead of a single misleading "average" — you can see where a quote sits in the real distribution.
